Plane carbon commutator and its manufacturing method

摘要

In a plane carbon commutator which is formed by fixing a plurality of metal segments to a commutator main body made of a resin and by integrally fixing a carbon to each of these segments, engagement projections provided in the carbon are engaged with engagement holes provided in the segments for a mutually fixed integration. Accordingly, it is possible to effectively utilize the characteristics of the carbon which has been burned at a high temperature in advance.
